Language input to practical dialogue systems must be trans- formed into a semantic representation that is customized for use by the back-end domain reasoners. At the same time, we want to keep front-end system components as domain independent as possible for easy portability across multiple domains. We propose a transparent way to achieve domain speci city from a broad-coverage domain-independent parser. We maintain a domain-independent ontology and de ne a set of mappings from it into a domain-speci c knowledge representation. We use the mappings to cus- tomize the semantic representations output by the parser for the reasoners, and to specialize the lexicon to the domain, which improves parsing speed and accuracy. This method facilitates our approach to instances of semantic type coercion common in our domains by combining lexical representations with domain-speci c constraints on interpretation.
